Various initiatives in Europe have been launched to study superconducting magnets for a rotatable gantry suitable to deliver up to 430 MeV/u carbon ions for hadron therapy. Different technologies and layouts are being considered: the baseline solution is developed within the EuroSIG collaboration and consists of a strongly curved cos-$\theta$ dipole based on the classical NbTi superconductor.

SC magnet design - EM part I
/ Farinon, Stefania (speaker) (INFN e Universita Genova (IT))
After a brief recap of the derivation of field harmonics, this lecture delineates the process of creating multipoles with current lines, focusing particularly on dipoles and quadrupoles. The presentation covers the derivation of ideal dipolar and quadrupolar fields, as well as more realistic cases such as sector coils and canted cos-theta configurations..

/ Zhao, Junjie (Lanzhou U.) ; Prioli, Marco (CERN) ; Stenvall, Antti (Tampere U. of Tech.) ; Salmi, Tiina (Tampere U. of Tech.) ; Gao, Yuanwen (Lanzhou U.) ; Caiffi, Barbara (INFN, Genoa) ; Lorin, Clement (Saclay) ; Marinozzi, Vittorio (Milan Bicocca U. ; INFN, Milan) ; Farinon, Stefania (INFN, Genoa) ; Sorbi, Massimo (Milan Bicocca U. ; INFN, Milan)
Protecting the magnets in case of a quench is a challenge for the 16 T superconducting dipole magnets presently designed for the 100 TeV: Future Circular Collider (FCC). These magnets are driven to the foreseen technological limits in terms of critical current, mechanical strength and quench protection. [...]

The Development of MBRD Magnets, the Separation/Recombination Dipoles for the LHC High Luminosity Upgrade
/ Farinon, Stefania (INFN, Genoa) ; Angius, Silvano (ASG Supercond., Genova) ; Barutti, Alberto (ASG Supercond., Genova) ; Bersani, Andrea (INFN, Genoa) ; Bracco, Michela (Genoa U. ; INFN, Genoa) ; Caiffi, Barbara (INFN, Genoa) ; Fabbricatore, Pasquale (INFN, Genoa) ; Fiscarelli, Lucio (CERN) ; Foussat, Arnaud (CERN) ; Gagno, Andrea (Genoa U. ; INFN, Genoa) et al.
As part of the high-luminosity upgrade of CERN LHC accelerator project, the National Institute of Nuclear Physics (INFN) in Genoa, Italy, has developed the MBRD separation-recombination dipole, also known as D2, whose function is to bring beams into collision before and after the interaction regions of the CMS and ATLAS experiments. It is a NbTi cos-theta double aperture dipole that generates a 4.5 T field in a 105 mm aperture, with a magnetic length of 7.78 m, and has the specific feature that the magnetic field in the two apertures is oriented in the same direction.

Validation of the Protection Scheme for the HL-LHC MBRD Magnet by Simulations and Prototype Tests
/ Caiffi, Barbara (INFN, Genoa) ; Bender, Lennard (Hochschule, Eng. Econ., Karlsruhe) ; Bersani, Andrea (INFN, Genoa) ; Bracco, Michela (INFN, Genoa) ; Farinon, Stefania (INFN, Genoa) ; Foussat, Arnaud (CERN) ; Gagno, Andrea (INFN, Genoa) ; Levi, Filippo (INFN, Genoa) ; Mangiarotti, Franco (CERN) ; Ninet, Gaelle (CERN) et al.
The High-Luminosity upgrade of the Large Hadron Collider (LHC) (Todesco et al., 2021) foresees the replacement of the magnets around the interaction points of the ATLAS and CMS experiments at CERN. One of the new magnets is the separation-recombination dipole, also called Main Bending Recombination Dipole (MBRD)(Caiffi et al., 2021), (Levi et al., 2022) in the D2 cryomagnet assembly. [...]

Following the recommendation of the Updated European Strategy for Particle Physics, an International Muon Collider Collaboration has been formed and is currently studying the feasibility of a 10 TeV center-of-mass energy muon collider facility. Several technical challenges must be faced, mainly due to the limited muon lifetime at rest, 2.2 µs. [...]

The recombination dipoles MBRD for the High Luminosity upgrade of the Large Hadron Collider (HL-LHC) at CERN are double-aperture superconducting magnets generating a central magnetic field of 4.5 T in a 105 mm diameter bore, directed in the same direction in both apertures. The integrated magnetic field is 35 T-m in a magnetic length of 7.78 m: with respect to the corresponding magnet presently installed in LHC, the aperture is larger, the length is smaller and the central field is higher.
